The Beast is heading to Hawaii..

... where it will gather photons and help to test software and hardware for AP. It has been cloudy here all month with no end in sight, so it is being shipped off to sunnier and warmer climes. My beautiful model is there for perspective to show just how big it is: 1600 mount with 120lb of counterweight and 305mm F3.8 Honders astrograph. Solid as a rock on its ATS pier. Hope to get some images in the coming week.

Holding the weights up with a step ladder sounds like the mount is in park 1 or park 4 [perhaps even park 5] when the scope is removed??

Everyone who has been using telescopes for very long (50+ years for me) has his or her own way of doing things that work. Tony was just showing us his technique for his AP 175. He was not advocating it for anyone else. 
You might be horrified to see me (with  help) mounting a big scope with the counterweights held up by a step ladder. Holding the counterweights up while removing the scope is important because once the scope is removed, the counterweights will swing down potentially crashing into me! I don’t suggest anyone use this technique but, I have used it successfully for decades, without incident.

My video is with a 175 refractor, not what you mention below. Various scopes may require other techniques. Also, what one person can accomplish another may not be able to. Just showing my way. I have absolutely no problem with the way I do it. We are talking about perhaps 50 lbs. That's not much weight, at least for me. I do consider myself to be in good shape though. I have a treadmill in my living room which I use twice a day and stay very active.

You will see that I have a handle at the center of balance. I can easily pick up the scope with my left hand and use my right hand on the base of the dovetail. Lifting it up and placing it in the saddle as I describe. The handle gives me a secure grasp of the scope. Depending where I place my mount on my property I may have to carry the 175 several hundred feet to get it to the mount from inside my house. No issues. A simple lift onto the mount is nothing after that.

No way would I try to mount the scope with rings opened and laying the scope in them. But that's me. Not everyone would agree.

BTW, send me that brand new PlaneWave 14 and I will demonstrate. One caveat, you won't be getting it back :)   {I wouldn't own a C14 or a Meade 16}

You were lucky because normally there is drift due to atmospheric refraction. The object must have been fairly high in the sky.

Folks,

Folks, I appreciate the kind comments.

Rolland, The mount was aligned with a PoleMaster.  Images were acquired without the use of a guide camera.  I went out again last night.  This time I acquired 33 five minute frames (unguided).  The results are here:

And by the way, there were actually two minor planets captured in the images:  796 Sarita and 793 Arizona.

So this is my first time imaging my home state's namesake nebula.  I took a bit of RGB for the stars.  I'm testing out Russell Croman's new StarXTerminator plugin for PixInsight, and it does a much better job of removing stars than starnet.  It's considerably faster as well.

I was originally intending to orient this upright like a CA map, but I'm not a fan of images with this skinny aspect ratio in a portrait orientation and I didn't want to crop anything.  Now had I done a mosaic or sprung for the full frame QHY600 and had more to work with, I probably would have.

Sounds like a great day Alan! Our warm Fall days are not going to last much longer.

Our single stack Lunt 80 is nicely hosted on Sue's well used and well traveled AP 400 QMD.

A nice day to be outside. I left the scope out for a couple of hours, taking breaks from working in the yard and garage for some solar views.


Clear skies, Alan

Occasional imaging opportunities are starting to reappear in Central Florida after a lengthy cloudy summer.  Last night I traveled to my nearest local dark sky site and imaged a number of winter deep sky objects including Pleiades.  I was able to acquire 20 three minute frames in between some pesky clouds with the Stowaway (& Telecompressor) and the Mach2GTO.  To my delight, I 'discovered' Minor Planet 796 passing near Pleinoe after processing the approximately 60 minutes of data.
